clk: qcom: gpucc-sdm845: fix clk_dis_wait being programmed for CX GDSC
[ Upstream commit cb81719e3c1165ef1bc33137dc628f750eed8ea4 ] The gdsc_init() function will rewrite the CLK_DIS_WAIT field while registering the GDSC (writing the value 0x2 by default). This will override the setting done in the driver's probe function. Set cx_gdsc.clk_dis_wait_val to 8 to follow the intention of the probe function.
